Where this page's figures come from
Generated 2026-09-28 21:02 by Hydrohistorian. Sources: DWR HydroBase snapshot HydroBase_CO_20260707 (history) + CDSS REST (current), USGS NWIS cross-checks. Engine v0.5.0 (35e2f2c) — every figure regenerates from this named code version and data image.
In short
In a median year over its last 12 recorded years it diverts 124 acre-feet.
Assembled from the figures on this page — every number above is checked against them before it is shown (2 checked). The detail, with its method, is in the cards below.
Well permit on file (1)
DWR ties this well permit to WDID 2007031. A permit is the authorization to construct and use the well — not a water right, and separate from the decrees on this page (three things called “well”).
| Permit | Use | Status | Depth | Static level | Yield | Completed |

What is in the bundle
rights.csv— every decreed right, most senior first, with admin numbers, dates, amounts, uses and case numbers.annual_use.csv— recorded diversion by year, with releases accounted separately.curtailment_now.csv— each right's current priority status and how often it was out across analog years.court_cases.csv— the cases attached to its rights.co_parties.csv— the other structures that were parties to those cases. Not available anywhere else.call_climatology.csv— how often each right has been out of priority by week of season, with confidence intervals and the seasons the record could actually judge.README.txt— provenance, methods, limits, disclaimer, and links back to DWR's own records for verification.

Which of its rights are out of priority?
The outlook for the weeks ahead is not computable for this structure: no decreed right on file, so there is no priority to test.
Recorded use (last 15 years on record)
Years far under the decreed amount? That gap has a name — paper water vs. wet water, explained on this structure.
In a median year this structure has a recorded diversion of 124 AF. Its most recent year on record, 2025, came in at 99 AF — 80% of that, and 2nd lowest of the 12 years with a recorded volume.
This structure records both diversions and reservoir releases — they are separate water movements and are accounted separately below.
| Year | Diverted (AFA volume: one acre covered a foot deep, about 326,000 gallons -- roughly a suburban household's outdoor use for a year.) | Compared with its own record | Released (AF) | Days recorded | Peak (cfs) |

Trends for this structure
Recorded use shows no clear trend over its last 12 recorded years — which is itself worth knowing.
How good is our record of it?
Grade C (5/10 points) — the components below are the finding; the letter alone is not.
The rubric, component by component
| Check | State | Detail |
|---|---|---|
| identity | complete | name, type, and water source all on file |
| decreed rights | absent | no water rights cached for this WDID |
| diversion record | present | 1159 measured days; currency unknown (no data-coverage date to compare against) |
| record continuity | sparse | 18% of the irrigation seasons in 1995-2025 carry measured days |
| published-record stability | stable | no upstream revisions recorded against this structure |
